【摘要】 研究了十字花科蔬菜不同品种问布局、轮作、间种和田间清洁对小菜蛾种群数量的影响。合理布局、轮作间种的田块,小菜蛾总虫量显著低于十字花科连作田,天敌种类的发生量高于对照连作田,与非十字花科蔬菜作物间作的田块,小菜蛾卵量、总虫量与对照区相比达显著差异,上述结果表明采用农业防治措施可有效地减轻小菜蛾的危害。更多还原

【Abstract】 The effects of cultural measures, such as inter-cropped, reasonable rotation, field sanitation on the Dia-monback moth (DBM) was evaluated in the base of the investigating population dynamics.Damage of DBM was significantly reduced when crucifer vegetables were planted in inter-cropped with spring onion, tomatoes, and kidney bean.Reasonable rotation was also of benefit to suppressing the DBM population densities.For example, the densities of DBM on growing manner of radish-towel gourd- "49 Ceixin" had made much lower than the manner of singly growing crucifer vegetables repeatedly.Phyto-sanitation was found so important for destroying the larvae and pupae remained on the debris after harvesting.更多还原
